Zurn Wilkins 1-70XLDUC 1 Inch 70XL Pressure Reducing Valve with Double Union FNPT & FC (Cop/Sweat) Union Connection - Ideal for Residential & Commercial Plumbing Systems

We are gifted with 110 PSI water pressure at the tap. When I repiped the house with 1" copper, I noticed the very annoying sound of water flow in the downstairs bedroom ceiling it runs through. I tried quieting it with extra thick foam pipe insulation, commercial grade Holdrite style acoustic pipe isolators, and even a suspended ceiling. I planned to go back and increase the pipe diameter in that particular room just to slow the flow, when the helpful folks at the Terry Love plumbing forums suggested I check my water pressure.If you can solder, and have access to about 6 inches of straight copper where the water service enters the house, you can install this in not much time. The only potential "gotcha" is to make sure you put the two nuts on the copper before installing / sweating the two large brass flanges that seat the valve. Other than that, it's about as straightforward an installation as it gets. Mine came preset at 65 PSI, and that's exactly what my pressure gauge read when I checked after installation.
